KST A12-S Magnetic Sensor Servo
The KST A12-S shares the same length and width as the popular X10, but features a slightly thicker 12mm profile for increased performance. Designed for large-scale and GPS gliders, aerobatic gliders, and turbine jets, it combines a 7-phase coreless motor with a wear-free magnetic sensor for fast, precise, and reliable control. The 25T-6 Futaba-standard output ensures compatibility with a wide range of setups.

Features
- 7 Phase Coreless DC Motor
- Contactless (Magnetic Sensor)
- Programmable
- Compact and Lightweight Design
- Excellent Torque and Speed
- Excellent Heat Dissipation
- Designed for High Performance RC Gliders
